WIREMAT.

SPECIFICATION forming part of Letters Patent No. 558,015, dated April '7, 1896.

Application iiled July 3, 1895. Serial No. 554,910. (No model.)

To all whom t may concern:

Be it known that I, WILLIAM ELMEs, a citizen4 of the United States, residing at Beaver Falls, in the county of Beaver and State of Pennsylvania, have invented certain new and .useful Improvements in Wire Mats; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to an improvement in that class of iioor-mats which are composed of various forms of coiled or crimped wire. Heretofore such mats have been made in such manner as to be heavy and cumbersome, requiring a large amount of wire in their construction, being expensive to manufacture and so designed as to prevent the free passage of mud or soil through from the top side when used as a scraper or outside door-mat. Another objection is their tendency to warp and turn up at the edges or corners, owing to defects in the principle of construction.

The obj ect of my invention is to provide a wire mat that will be free from all these objections, and with this in view I have made a mat of such form and material as will best secure the results desired.' It is of few parts, light and open in mesh, simple and cheap to manufacture, and is durable in use, and it will lie fiat Where placed, yet may be rolled into a close roll for shipment or storage, which is a great advantage.V A coil in flattening or turning up follows the line of least resistance. That in a right coil is in the direction of the pitch--to the right. In a left-hand coil it is toward the left. To obviate this evil, I use alternately a coil of right and a coil of left hand The coils placed in this position give the mat a corrugated surface, which makes a better scraping surface than on those formerly constructed, yet is almost as Iiexible as carpet and is so open that dirt will readily fall through it.

Referring to the drawings,part of this specification, Figure l represents a plan view of a portion of a wire mat, and Fig. 2 an elevation or edge view of same.

It will be understood that the mat may be extended or enlarged in either direction indefinitely to cover the area of any floor.

In practical application the coils A and B are formed and alternately connected in a machine with an intertwining tie-wire having alternating right and left loops or links C C, which securely hold the coils together.`

A represents a right-hand coil and B a lefthand coil. At the border end of each of these coils a loop is turned so that the terminating loop of the tie-wire binds and prevents the coilsfrom shifting or crawling endwise, yet the tying permits the mat to be close-rolled when desirable. When lying flat, the effect of the pressure upon a rightcoil is counteracted by the left coil,`and vice versa, thus preventing the turning up of the mat at the sides or corners, as usually occurs in other wire mats.

Although, as shown in the drawings, a tiewire is represented as connecting three coils, it is obvious that two coils may be connected by each tie-wire without departing from the intents and purposes of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is I l. A wire mat comprising a series of wire coils placed parallel with each other and connectedby binding-wires, said coils being made some with a right-hand pitch and some with a left-hand pitch respectively and laid side by side so that they alternate right and left hand with each other, said binding-wires having side loops turned in them alternating right and left, the said binding-wires and loops being intertwined through the said coils in an approximately parallel direction with them, so that each binding-wire and its loops connect and hold togetherthree or two of said coils, said series of coils being so connected indefinitely to form said mat of any desired size, substantially as and for the purpose shown and described.

2. In a wire mat the combination of coils having right and left hand pitch placed alternately and connected in series of three or two coils each by a single binding-Wire to each series, said binding-wire having alternating right and left loops, substantially for the purpose set forth as shown and described.

In testimony whereof I afx my signature in presence of two witnesses.

WILLIAM ELMES.
